Affymetrix GeneChip® Exon and Gene Arrays offer a more complete and accurate picture of overall gene expression than traditional 3'-based expression arrays, by enabling you to interrogate the entire length of the gene, not just the 3' end. Combined with the GeneChip® Whole Transcript Assay, you not only get a more accurate picture of whole-genome, whole-transcript gene expression, but you can also see precisely what is being expressed.
Whole Transcript and Alternative Splicing: Exon 1.0 ST Arrays
GeneChip Exon Arrays provide the most comprehensive coverage of the genome and enable two complementary levels of analysis-gene expression and alternative splicing. Multiple probes per exon enable “exon-level” analysis and allow you to distinguish between different isoforms of a gene. This exon-level analysis on a whole-genome scale opens the door to detecting specific alternative splicing events that may play a central role in disease mechanism and etiology. You can also perform “gene-level” analysis, in which multiple probes on different exons are summarized into a single expression value of all transcripts from the same gene, enabling similar analysis workflows to 3'-gene expression.
Whole Transcript: Gene 1.0 ST Arrays
The Gene 1.0 ST Array System offers a cost-effective solution for whole-genome, whole-transcript expression analysis for human, mouse and rat. Each of the well-annotated genes is represented by approximately 26 probes spread across the full length of the gene, providing a more complete and accurate picture of gene expression than 3'-based expression array designs. All 26 probes are automatically summarized into a single expression value per gene, allowing standard analysis software packages and simple analysis workflows to be used to analyze data. Gene 1.0 ST Arrays are the most advanced and cost-effective gene expression profiling option for new microarray users.
